What is the definition of earthing and how it works?
It is a step up or step down for power delivery.
An audio frequency transformer is a transformer designed to operate in the range of frequencies audible to the average human. This range is generally accepted to be from 20 Hz to 20,000 Hz. The usual purpose of an audio transformer is to match impedances between circuit sections. For example: between a microphone and the input of an amplifier, (input transformer), or between the output of an amplifier and the loud speaker. (output transformer).
Without a load the secondary current is zero, by definition.
An industrial transformer is a specialized electrical device designed to manage high-power applications and ensure the safe, efficient transfer of electrical energy across circuits in demanding industrial environments. Its primary function is to step up or step down voltage levels to meet the requirements of heavy machinery, manufacturing systems, and power distribution networks. Engineered for durability, these transformers can withstand extreme temperatures, continuous operations, and electrical surges, ensuring long-term reliability and minimal downtime. Industrial transformers are essential for maintaining power quality, voltage stability, and equipment safety. They help minimize transmission losses, isolate electrical faults, and deliver a steady voltage supply — all of which are critical for uninterrupted industrial performance. The most common types include power transformers, distribution transformers, isolation transformers, and control transformers, each designed for specific operational needs and power demands.

a hole transformer
Transformer has windings
The Load will consume part of the power and therefore reduce the current (voltage ) available for the secondary part of the transformerAnswerYou cannot apply a load to the primary of a transformer which, by definition, is the winding connected to the supply voltage. Your question makes no sense.
yes we can place auto transformer in place of original transformer
Transformer is by definition can transform only AC current. But it's possible to build device that can step up or step down DC voltage directly. These are called DC-DC converters not transformers.
In power transformer, a differential relay is a relay that verifies the balance of current between the primary and the secondary face of a transformer. It is also employed in other components of the power system like in protecting cables. Differential relay is also called a unit protection.
A transformer that increases voltage is a step-up transformer.
